Introduce bpf_xdp_ct_alloc, bpf_skb_ct_alloc and bpf_ct_insert_entry kfuncs in order to insert a new entry from XDP and TC programs. Introduce bpf_nf_ct_tuple_parse utility routine to consolidate common code. We extract out a helper __nf_ct_set_timeout, used by the ctnetlink and nf_conntrack_bpf code, extract it out to nf_conntrack_core, so that nf_conntrack_bpf doesn't need a dependency on CONFIG_NF_CT_NETLINK. Later this helper will be reused as a helper to set timeout of allocated but not yet inserted CT entry. The allocation functions return struct nf_conn___init instead of nf_conn, to distinguish allocated CT from an already inserted or looked up CT. This is later used to enforce restrictions on what kfuncs allocated CT can be used with.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
